LONDON -- Sony Computer Entertainment has pinkslipped an unspecified number of staff at three of its U.K.-based vidgames studios.

The games developers, Evolution Studios, Guerrilla Cambridge and SCE London Studio, have each lost "numerous" staffers, according to the website Videogamer.

A SCE spokesperson confirmed to Variety that there had been layoffs, but didn't state how many.

"Regular reviews take place throughout SCE Worldwide Studios, ensuring that the resources that we have in such a competitive business can create and produce high quality, innovative and commercially viable projects," the SCE spokesperson said.

"As part of this process, we have reviewed and assessed all current projects and have decided to make some changes to some of our European studios. As a result of this, there will be a focused restructure within London Studio, Guerrilla Cambridge Studio and Evolution Studios to ensure that the SCE WWS is in the best position to achieve their goals going forward.

"Our first party development studios are key to our creative strategy and we are very excited about the future projects being worked on."

Evolution, whose past credits include "World Rally Championship" and "MotorStorm," is developing the much hyped PlayStation 4 racing game "DriveClub," which was recently sent "back to the drawing board," according to Scott Rohde, PlayStation software product development head for Sony Worldwide Studios America.

Sony said that the "development of 'Driveclub' will not be affected" by the layoffs.

It also emerged Tuesday that the game director on "Driveclub," Col Rodgers, ankled Evolution last month.

Guerrilla Cambridge, which is best known for its "MediEvil" series, wrapped work on PlayStation Vita first-person shooter game "Killzone Mercenary" last year.

SCE London Studio completed work on PS4 game "The Playroom" last year. It developed the "EyeToy" and "SingStar" franchises, which pioneered the concept of social gaming.
